mmlu_train_62571 | As we get older, most of us worry about grey hair, wrinkles and maintaining a youthful body. But people often don't realize the voice needs looking after. Here, Mr. Rubin, a voice expert, reveals how to keep your voice youthful. Drink more fluid and avoid spicy food You need water for the vocal cords to vibrate well. The body must be kept hydrated enough to make the vocal cords operate well. Drinking 1.5 liters of water a day at intervals of 15 minutes is very important. Mr. Rubin advises avoiding foods with an annoying effect on the stomach, such as onions, chili, fizzy drinks and chocolate. Rest the throat and talk regularly The vocal cords can be scared if you use your voice during a bad cough. If you have a case of laryngitis with a cold, you should rest your voice for a day or two, and seek medical advice. Simply staying sociable and using your voice is very important. "As older people get less mobile, they can become socially isolated and speak less." says Mr. Rubin. "The elderly need to communicate with people more. By using the vocal cords, they enable the ageing process to slow down. " Improve your posture Good posture is essential to keeping the voice young, so we'd better stand properly. Exercise helps you take deeper breaths as it means there is better airflow through the voice box, producing a stronger tone. Sing in the shower This is one of the best ways to preserve your voice, as it keeps the larynx muscles strong while the steam lubricates the voice box. "Singing is gymnastics for the voice," says Mr. Rubin. Joining a choir is one of the best ways to preserve a youthful tone. To protect the voice, the old people should _ . | [

mmlu_train_54670 | In the near future, we may be using our eyes to operate our smartphones and tablets, even when it comes to playing popular games like Fruit Ninja. The GazeGroup has been developing eye-controlled computer technology for nearly 20 years. But those devices have been mainly designed to aid those with disabilities, and are very expensive. "After a while, we figured out that probably the best way is to go for a mass-market approach," says Gaze's Sune Alstrup Johansen, "where everybody would have this available." Johansen and some of his colleagues have formed a new company, The Eye Tribe, which is hoping to develop the technology on a mass commercial level. The technology works by sending an infrared light from the computing device toward the user's face. After measuring the user's eye movements, the technology is then able to easily know where a person's eyes are moving, allowing the eyes to control a cursor . A software can determine the location of the eyes and tell where the user is looking on the screen. It even knows which image he is looking at. There has been a gradual change toward hands-free technology in recent years, particularly in the gaming world. Following Nintendo's popular Wii system, Xbox released the Kinect device, which lets users control their Xbox and play certain games using only their hands, legs and voices. Since most smartphones and other mobile devices can't come standard with an infrared device, Johansen said a replaceable filter would be an inexpensive, convenient choice for most consumers. And even as companies like The Eye Tribe work to create a commercially practical product for the average user, making the eye-controlled technology more accessible and less expensive will have similar benefits for disabled users. "Then I can go to any computer, and then I can control it and I can use it, instead of just bringing my own," said Stig Langvad, who heads up Denmark's umbrella organization for people with disabilities. "So I'll be a part of society on an equal foot, instead of being a special solution." Which the following statements about The Eye Tribe is true? | [

mmlu_train_61545 | More than 27,000 people from around the UK set off at dawn from London to begin the cycle route through Surrey to the Sussex coast. The annual 54-mile ride raises money for the British Heart Foundation(BHF) and is Europe's largest charity cycling event. Cyclists began the exhausting journey at Clapham Common at 6 a. m. , hoping to reach Brighton seafront within an average of six hours. Money from today's event will help the charity to continue its vital work through heart research and the development of its care and support services. Among those taking part was BBC Breakfast's resident Dr Rosemary Leonard and several colleagues. BHF spokeswoman Gemma Cloke said, "It was quite cold this morning, but everyone set off without any problems." Those taking part range in age from 14 to those in their 70s. Last year cyclists raisedPS4. 1 million for the charity, and have raised more thanPS50 million since the BHF became involved in the event in 1980. The first ride was held in 1976. It is hoped this year's fund raising total could reachPS4. 5 million. She added : "We have a lot of people taking part, from the more experienced cyclists to those cycling with friends and family in memory of someone and to raise money through sponsorship." "People are always pleased knowing the money is going to a good cause. There is so much support along the route, with local residents watching the ride.

mmlu_train_20044 | A global positioning system(GPS)service is aiding the elderly in the Panlong district of Kunming,capital of Southwest China's Yunnan province. The telecommunications service provider,with the support o,f the local govemment,started the GPS tracking service in January to help the elderly,especially those with Alzheimer's disease,a condition that slowly destroys memory. Huang Haiying,an employee with a local telecommunications company,told China Daily that with the GPS devices ,the people who look after the elderly can quickly find their positions either online or by ca l l ing the service center in case ot emergencles. The system is also connected to the police,hospitals,fire services and community service centers to ensure that the elderly get quick and proper help,Huang said. Experts said that this service could improve the quality of life for thousands of elderly people with Alzheimer's,their families and those who look after them. Hundreds of people have already been helped by the service this year,Huang said. Huang said that the system has about 1 0,000 subscribers and she expects that number to grow 1 0 times over the next three years.A user pays 25 yuan($4)each month for the service.A family with an income below the local poverty line can get a 10 yuan subsidy evcry month from the government. The local government has spent more than 2 million yuan to subsidize the service to date.

mmlu_train_33600 | Older people with hearing loss may suffer faster rates of mental decline. People who have hearing trouble suffered meaningful impairments in memory, attention and learning about three years earlier than people with normal hearing, a study published online January 21 in JAMA Internal Medicine reveals. The finding supports the idea that hearing loss can have serious consequences for the brain,says Patricia Tun of Brandeis University in Waltham,Mass., who studies aging. "I'm hoping it will be a real wake-up call in terms of realizing the importance of hearing. " Compared with other senses, hearing is often overlooked, Tun says. "We are made to interact with language and to listen to each other, and it can have damaging effects if we don't." Frank Lin of Johns Hopkins School of Medicine and colleagues tested the hearing of 1,984 older adults. Most of the participants, who averaged 77 years old, showed some hearing loss -- 1,162 volunteers had trouble hearing noises of less than 25 decibels, comparable to a whisper or rustling leaves. The volunteers; deficits reflect the hearing loss in the general population: Over half of people older than 70 have trouble hearing. Over the next six years, these participants underwent mental evaluations that measured factors such as short-term memory, attention and the ability to quickly match numbers to symbols. Everybody got worse at the tasks as time wore on, but people with hearing loss had an especially sharp decline, the team found. On average, a substantial drop in performance would come about three years earlier to people with hearing loss. Lin cautions that the study has found an association between hearing loss and mental abilities; the researchers can't conclude that hearing loss directly causes the decline. Yet more and more studies are turning up ways that diminished hearing could damage the brain. A person who can't hear well might avoid social situations, and isolation is known to be bad for the brain. "You gradually become more socially withdrawn, " Lin says. "Social isolation is a major, major factor for dementia and cognitive decline. " Other studies suggest that when people struggle to interpret and decode words, their brains _ energy away from other tasks, such as memory. Audiologist and psychologist Kathy Pichora -- Fuller says that this brain drain happens to everyone, even people without hearing loss. Studies have shown that people are worse at remembering things when they're in a noisy room, for instance. People with hearing loss may be constantly diverting a large swath(--)of their brainpower,leaving less for other mental tasks, says Pichora-- Fuller, of the University of Toronto Mississauga.

mmlu_train_43781 | Food picked up just a few seconds after being dropped is less likely to contain bacteria than if it is left for longer periods of time, according to the findings of research carried out at Aston University's School of Life and Health Sciences. The findings suggest there may be some scientific basis to the "5 second rule" --- the belief about it being fine to eat food that has only had contact with the floor for five seconds or less. Although people have long followed the 5 second rule, until now it was unclear whether it actually helped. The study, undertaken by final year Biology students and led by Anthony Hilton, Professor of Microbiology at Aston University, monitored the transfer of the common bacteria from a variety of indoor flooring types (carpet, cement floor etc.) to toast, pasta, a biscuit and a sticky sweet when contact was made from 3 to 30 seconds. The results showed that: Time is a significant factor in the transfer of bacteria from a floor surface to a piece of food; and the type of flooring the food has been dropped on has an effect, with bacteria least likely to transfer from carpeted surfaces and most likely to transfer from cement flooring surfaces to moist foods making contact for more than 5 seconds. Professor Hilton said: "Consuming food dropped on the floor still carries an infection risk as it very much depends on which bacteria are present on the floor at the time." The Aston team also carried out a survey of the number of people who employ the 5 second rule. The survey showed that: 87% of people surveyed said they would eat food dropped on the floor, or already have done so. 55% of those who would eat or have eaten food dropped on the floor are women. 81% of the women who would eat food from the floor would follow the 5 second rule. Professor Hilton added, "Our study showed that a surprisingly large majority of people are happy to consume dropped food, with women the most likely to do so. But they are also more likely to follow the 5 second rule." According to the passage, which of the following is true? | [
"A toast dropped on the carpet is easier to be polluted than that dropped on the cement floor.",

mmlu_train_40870 | If you want to improve your child's results at school, you could do a lot worse than ensuring that they do plenty of exercise. Scientists have already shown that physical activity can make you brainier. But a team in America has used scans to show that an important part of the brain actually grows in children who are fit. These youngsters tend to be more intelligent and have better memories than those who are inactive. Scientists also found that one of the most important parts of their brains was 12 percent larger than those of unfit children. They believe that encouraging children to take exercise from a very young age could help them do better at school later. Researchers from the University of Illinois, in the U.S., studied the brains of 49 children aged nine and ten using a magnetic resonance imaging scan , a technique which provides very detailed pictures of organs and tissues in the body. They also tested the fitness levels of the children by making them run on a treadmill . The scientists found that the hippocampus, a part of the brain responsible for memory and learning, was around 12 percent larger in the fitter children. Professor Art Kramer, who led the study published in the journal Brain Research, said the findings had important implications for encouraging individuals to take part in sport from a young age. "We knew that experience and environmental factors and socioeconomic status all impact brain development," he said. "If you get some terrible genes from your parents, you can't really fix that, and it's not easy to do something about your economic status. But here's something that we can do something about."

mmlu_train_29908 | It's impossible to determine how many people would have lost their lives without the contribution of African-American inventor Dr Charles Drew. Charles Drew was born on June 3, 1904, in Washington, DC. His early interest was in education, but he was also an outstanding athlete. While in college, he was awarded as the man who contributed the most to sports during his four years in school. Drew's sister Elsie suffered from tuberculosis and died in 1920. Her death influenced his decision to study medicine. After becoming a doctor and working as a college instructor, Drew went to Columbia University, where he earned his Doctor of Medical Science degree. During this time he became involved in research on blood and blood transfusions. At Columbia, he wrote a paper on "banked blood", in which he described a technique he developed for the long-term preservation of blood plasma. Before his discovery, blood could not be stored for more than two days because of the rapid breakdown of red blood cells. Drew had discovered that by separating the plasma from the whole blood and then refrigerating them separately, they could be combined a week later for a blood transfusion. Drew became the first African American to receive a PhD in medical science. After World War II broke out, Drew was called upon to put his techniques into practice. He was named a project director for the American Red Cross but soon quit his post after the government issued an order that blood taken from white donors should be separated from that of black donors. On April 1, 1950, after he attended the annual free clinic at the John A. Andrew Memorial Hospital, he and other three physicians decided to drive back home. As he was tired from spending the night before in the operating room, he lost control of his car. Drew was badly injured and was taken to Alamance General Hospital in Burlington, North Carolina. He was pronounced dead half an hour after he first received medical attention. Drew's funeral was held on April 5, 1950, at the Nineteenth Street Baptist Church in Washington, DC. But contrary to popular thought, he was not refused a blood transfusion by an all-white hospital. He indeed received a transfusion but was beyond the help of the doctors attending to him. As Dr. John Ford, one of the doctors who survived the accident, later explained, "We all received the very best of care. The fact that he was a Black did not in any way limit the care that was given to him." Over the years, Drew has been considered one of the most honored figures in the medical field.

Many people would prefer drinking green tea than white tea and black tea, simply because of its _ aroma not found in other types of tea. Nowadays, keeping the natural greenish color1 of tea leaves remained just like before. This is done by preparing the green tea just like the way it was prepared before--by washing the leaves right after pulling off them from the bush, then boiling them. There have been many healthful claims saying that drinking green tea-based products help a lot in improving the general health of their body. For a long time, there has been many beliefs saying that green tea can help, cure beriberi disease , treat wounds, and even prevent tiredness. Now modern technology determines that there are even added healthful benefits that include reducing the possibility of having a heart disease and helping people to lose more weight easily. Besides, studies have found out that green tea has Polyphenols , a type of flaonoid that greatly reduces the amount of time of cell maturation. The flavonoid found in green tea is called EGCg- a stronger matter than Vitamin C and E. It is believed to be 20 times stronger than these mentioned vitamins. Having two cups of green tea daily is a good routine for your body. However, most doctors would suggest drinking at least 4 cups a day is the best. You can slowly increase the amount of drinking it to allow your body to get used to it. There is nothing to lose but everything to gain in drinking green tea.

mmlu_train_24224 | India was once part of the British Empire, but thanks to modern technology and a booming economy, it has turned the tables on its former colonial master. Indian tutors are helping to teach math to British children over high-speed Internet connections. Early results suggest the idea is improving exam results. But not everyone is happy at this "outsourcing" of tutoring. It's 3:30, and pupils at Raynham Primary School in London are gathering for their after-school maths lessons. Five time zones-- thousands of kilometers away--their math tutors are also arriving for class. High-speed Internet has made it possible for Indian tutors to teach British pupils in real time. Each pupil gets a dedicated one-to-one online tutor. The students work with activities on their computer screen and wear a headset and microphone to talk to their tutor. The class teacher, Altus Basson, says he has seen an improvement in results. "There are some children who've really rocketed in their results. Children who struggleto focus in class focus a lot better on the laptops. The real advantage is that each child gets a focused activity and a single tutor," he said. Such individualized teaching is the core idea of Brightspark Education, the company that provides the online tutoring, says founder Tom Hooper. "Children today feel very confident online; they feel very engaged; they feel very in control. And that's half the battle with education.Give them control, make them feel confident and enjoy their learning and you'll see them start to improve and embrace it," he said. Raynham Primary School is among the first in Europe to try online tutoring. At between $20 and $25 an hour, it's about half the cost of face-to-face coaching. But some people say an Internet connection is not enough of a connection for teaching and learning. Kevin Courtney is deputy General Secretary of Britain's National Union of Teachers. "We think, there's a really important emotional connection between a teacher and a child whether it's a whole class or whether it's one-to-one. You need that immediacy of feedback and we're not convinced that that can happen across an Internet connection. In one of the wealthiest.countries in the world, we think that we can afford to have teachers with genuine emotional connection there with the children," he said. Brightspark Education says the online tutoring is used only as an addition to supplement regular teaching. The company says its service does not represent a threat to teachers' jobs in Britain. Parents say they're very satisfied with the results they've seen. And what about the children?Children: "I love it!"I love it!"I hate maths!" So math--or, as the British call it, maths--is still not everyone's favorite subject even with the latest technology to teach it. According to Kevin Courtne, _ . . | [

mmlu_train_12924 | The crisis at the damaged Fukushima Dai-Ichi Nuclear Power Station in northern Japan has raised worries about radiation risks. We spoke Tuesday with Jonathan Links, an expert in radiation health sciences. He is a professor at the Johns Hopkins Bloomberg School of Public Health in Maryland. Professor Links says workers within the nuclear plant are the only people at risk of extremely high doses of radiation. JONATHAN LINKS: "Of course, we don't know what doses they've received, but the only persons at risk of acute radiation effects are the workers." For other people, he says, there may be a long-term worry. People can get cancer from low doses of ionizing radiation, the kind released in a nuclear accident. Professor Links says scientists can use computers to quickly model where radioactive material has blown and settled. Then they measure how large an area is contaminated. He says if the situation is serious enough, officials could take steps like telling people not to eat locally grown food or drink the water. JONATHAN LINKS: "But that would only be the case if there was a significant release and, because of wind direction, the radioactive material was blown over the area, and then settled out of the air into and onto water, plants, fruits and vegetables." The reactors at Fukushima are on the Pacific coast. But Professor Links says people should not worry about any radioactive material leaking into the ocean. JONATHAN LINKS: "Even in a worst-case scenario accident, the sea provides a very high degree of _ . So the concentration of radioactivity in the seawater would still be quite low." Japan is the only country to have had atomic bombs dropped on it. That memory from World War Two would create a stronger "psychological sensitivity" to radiation exposure, Professors Links says. Next month is the twenty-fifth anniversary of the explosion and fire that destroyed a reactor at Chernobyl in Ukraine. The nineteen eighty-six event was the world's worst accident in the nuclear power industry. A new United Nations report says more than six thousand cases of thyroid cancer have been found. These are in people who were children in affected areas of Belarus, Russia and Ukraine. The report says that by two thousand five the cancers had resulted in fifteen deaths. The cancers were largely caused by drinking contaminated milk. The milk came from cows that ate grass where radioactive material had fallen. To get the latest updates, go to www.unsv.com.

mmlu_train_50502 | Over the years, Americans have become used to salt. Most people have no idea how much salt they consume --on average, about 9 to 12 gram per person per day, according to the American Heart Association. That's twice the amount recommended by the government. A new study last week showed eating even a little less salt could greatly help the heart. The scientists said the results would be thirteen percent fewer heart attacks, eight percent fewer strokes , four percent fewer deaths and eleven percent fewer new cases of heart disease. Researchers also found that the benefits would be greatest for African Americans and women. As a group, African Americans tend to have higher blood pressure than the general population, and "many studies suggest that they may be more sensitive to salt," says Dr. Kirsten Bibbins-Domingo, an epidemiologist at the University of California, San Francisco. Her analysis found that a reduction of 3 gram of salt per day would reduce heart attacks 8% on average; among African Americans, that rate would drop 10%. A similar result was found in women, whose stroke risk dropped 8% with a 3-g reduction in salt intake; in men, the risk fell 5%. They and public health professionals in the United States are interested in a national campaign to persuade people to eat less salt. However, other scientists say such a campaign is an experiment with the health of millions of people. Michael Alderman, a high blood pressure expert and professor at Albert Einstein College of Medicine in New York, says that eating less salt results in lower blood pressure. But he says studies have not clearly shown that lowering salt means fewer heart attacks or strokes. "Salt has other biological effects. Calling for reductions in the national diet could have good effects, as well as harmful results. There is not enough evidence either way."

mmlu_train_40533 | The Massachusetts Institute of Technology (MIT) is a private research university in Cambridge, Massachusetts, founded in 1861 in response to the increasing industrialization of the United States. The institute stressed laboratory instruction in applied science and engineering. MIT's early emphasis on applied technology at the undergraduate and graduate levels led to close cooperation with industry. Curricular reforms under Karl Compton and Vannevar Bush in the 1930s emphasized basic science. MIT was elected to the Association of American Universities in 1934. Today, the institute comprises various academic departments with a strong emphasis on scientific, engineering, and technological education and research. MIT is one of the most selective higher learning institutions, and received 18,357 undergraduate applicants for the class of 2018 -- only admitting 1,419, an acceptance rate of 7.73%. MIT's 168-acre campus spans approximately a mile of the north side of the Charles River basin in the city of Cambridge. The campus is divided roughly in half by Massachusetts Avenue, with most dormitories and student life facilities to the west and most academic buildings to the east. MIT's on-campus nuclear reactor is one of the most powerful university-based nuclear reactors in the United States. In 1999 Bill Gates donated $20 million to MIT for the construction of computer laboratory named the "William H. Gates Building". While Microsoft had previously given financial support to the institution, this was the first personal donation received from Gates. Other notable campus facilities include a pressurized wind tunnel and a towing tank for testing ship and ocean structure designs. From the passage, we know MIT _ . | [

mmlu_train_28924 | Vitamins are complex chemical substances found in many foods. The human body needs them for health and growth. The body makes some vitamins, but usually in amounts too small to meet its needs. Other vitamins are not made in the body. These must be supplied. No one knows exactly how all vitamins work. Doctors do know that vitamins have very special uses. One vitamin therefore cannot take the place of another. The steady absence of one vitamin in an otherwise complete diet causes a deficiency disease. Rickets, scurvy, and pellagra are examples of deficiency diseases. It is best to obtain vitamins by eating the foods in which they occur. There are also pills that contain a single vitamin or a combination of vitamins people should consult their doctors before they take any vitamin pills. Scientists have discovered about 25 vitamins and their different forms that are very important to human beings and other forms of life. Experts believe that there are many more vitamins to be discovered. There are two basic groups of vitamins. One group of vitamins dissolves in fat and is therefore called the "fat-soluble" group. Vitamins A, D, E and K are in this group. The other group is known as "water-soluble" vitamins. These vitamins, understandably, dissolve in water. Among this group are Vitamin C and the B group of vitamins. Vitamin A aids the building and growth of body cells. This vitamin is therefore vital for the growth of children and for good development of babies before birth. Vitamin A is also important for good vision at night. Vitamin B1 is also called thiamine. This vitamin prevents and cures disease. Vitamin B2, called riboflavin, is needed for growth, healthy skin, and for the eyes. Vitamin C, or ascorbic acid, prevents and cures scurvy. Vitamin D is a group of 10 vitamins that prevents rickets. Scientist believe that Vitamin D3 forms in the skin when the body is exposed to sunlight. Because of this, it is called the "sunshine vitamin". A lack of Vitamin D may lead to bone damage; too much may cause kidney disease. All of the functions of Vitamin E, also called tocopherol, are not known. It is necessary for reproduction in animals. Vitamin K is necessary for making the blood clot. The more that is learned about vitamins, the more it is realized how these chemical substances play a part in all aspects of human activity. What can be inferred from the passage? | [

mmlu_train_14590 | (Natural News)Many parents have tried to gave their children a head start on education with get-smart videos and enrichment activities as early as infancy, but free play is often sacrificed, so the American Academy of Pediatrics says that the best medicine for busy children is an increase in traditional "playtime". A number of studies suggest that unstructured play can help children become creative, discover their own interests, develop problem-solving abilities, and relate to others socially, according to a report prepared by two academy committees for release Monday at the group's annual meting. On the contrary, a lack of such playtime can create stress for both children and parents, and it can also cause obesity when children spend too much time sitting in front of educational videos. The report notes lack of playtime could even lead to depression in many children. The report thinks the lack of playtime lies in the fact that parents want to have super-smart children and safe places for children to play is decreasing. A balance between free playtime and educational activities should be struck, the report states. "In the current environment, where so many parents feel pressure to be super parents, I believe this message is an important one," said Dr. Kenneth Ginsburg, the report's lead author and a pediatrician at The Children's prefix = st1 /HospitalofPhiladelphia. Noted pediatrician, author, and presenter of cable TV's "What Every Baby Knows," Dr. T. Betty Brazelton agreed.

mmlu_train_60399 | It's the dieting fashion that is sweeping the world, and encourages fasting for two days of the week. But does it work? People are starving themselves to lose weight, with a dieting trend known as the "fast diet" growing in popularity. The method is also known as the 5:2 diet, and consists of eating normally for five days of a week and cutting calories to about 25 percent of normal intake during other two days. Men consume just 600 calories on the two fast days, while women are limited to 500 calories. Notably, the two fasting days should not be _ . The dieter should have at least one normal eating day in between. In the best-selling book The Fast Diet: Lose Weight, Stay Healthy, and Live Longer with the Simple Secret of Intermittent Fasting by Dr. Michael Mosley and Mimi Spencer, the two authors claim that the 5:2 diet not only promotes weight loss, but also benefits health, offering protection from disease, improved cognitive function and increased lifespan. The diet originated in the United Kingdom and became popular in the United States. Now, it is gaining popularity among the Chinese middle-class. Zhong Minghui, who is 178 cm tall and used to weigh 100 kilograms, finds fasting effective in weight control. He works in the sales department of a trade company and used to drink and eat a lot after work. After sticking to the fasting diet for five months, he managed to lose about 20 kilograms. "Actually I did not exactly rely on the 5:2 diet to lose weight. My fasting was more extreme. I almost completely cut off my supper every day and only ate some fruit. I also used an app to calculate the calories in the food I ate and was cautious of not eating any high-calorie food. I did about an hour's aerobic exercise every day. Fasting is definitely effective, but I think sports also help," he says. "I do not really believe that fasting is the magical cure-all , but my high blood sugar has improved," he adds. The US Academy of Nutrition and Dietetics says that although there is evidence that intermittent fasting diets may help prevent chronic disease, more research is needed. Han Ting, a clinic nutritionist of Shanghai Tenth People's Hospital, says that people who suffer diabetes or eating disorders, pregnant women, kids, teens and frail seniors should not try fasting. She recommends a regular low-calorie diet, which is safer and less risky for health. When on a fasting diet, on the weekly fasting days, Han recommends low-fat, low-sugar, and low-protein food, such as vegetables, yogurt, non-fat milk, shellfish and fruits with high dietary fiber .

These questions have been put back into the spotlight recently. On Nov 19, the Food and Drug Administrati0n (FDA) in the US announced that it had approved the AquAdvantage salmon to go on the market, making it the first genetically modified animal to be approved as food anywhere in the world. GM foods are plants or animals that have been given a gene from another plant or animal to make them stronger in some way. The AquAdvantage salmon contains a gene from another type of salmon that makes it grow faster. Although the FDA has said "food from the fish is safe to eat", some believe that scientists can't completely understand the potential health risks of GM foods, simply because they're so new. Others worry that the fish could escape into the wild and cause ecological problems. GM crops have experienced the same controversy, even though GM technology cuts down on the use of pesticides on crops and increases yields. While GM animals are new, GM crops have already appeared on our plates: A total of 28 countries in the world including the US, Brazil and India planted 181.5 million hectares (1.815 million km2) of GM crops in 2014, according to the International Service for tile Acquisition of Agri-biotech Applications. In China, we grow GM cotton and papaya and import GM soybeans, corn, rape, cotton and beets from abroad. Due to safety worries, many countries have regulations for producing and selling GM food. In European Union countries, each GM food must be approved before it can be used. This process can take up to 17 months. The origin of all GM foods must also be traceable, and all food with a GM content of more than 0.9 percent must also be labeled, according to EU website europa.eu. The US is less strict about GM foods. According to FDA regulations, companies introducing new GM foods to the market should report them at least 120 days before release. The labeling is voluntary, except that a product cannot be labeled as "GM-free" if genetically modified materials are used.

When researchers at Tokyo University see a cockroach, they take the remote control and make the cockroach turn around, run left or right, or go forward. These scientists are changing the cockroaches into robots. Each cockroach has a very small pack that has in it a microprocessor .Then researchers can send signals from the remote control to the pack. The signals control the movements of the cockroaches. Why does anyone want to control a cockroach? "Insects can do many things that people can't," says Isao Shimoyama, head of robot research at Tokyo University. In a few years, he says, these robot insects will carry very small cameras. They will be able to move through earthquake rubble to look for people or move under doors to find information about someone. This may seem strange, but the Japanese government thinks the research is very important. The government is giving the scientists $ 5 million for this research. First, the researchers breed hundreds of cockroaches. They use only the American cockroach because it is bigger and stronger than other cockroaches. Then they choose the best cockroaches and remove their wings and antennae . They put small packs where the antennae were. The packs weigh about three grams, or about two times the weight of the cockroaches themselves. "Cockroaches are very strong," says Ralph Holzer, who is a researcher at Tokyo University. "They can lift 20 times their own weight. " With a remote control, the scientists send signals to the packs. When a cockroach gets the signal, it moves.

They said "cheers," clicked drinking bags and toasted NASA workers on the ground. The urine recycling system is needed for astronaut stations on the moon and Mars. It also will have NASA money because it won't have to ship up as much water to the station by space shuttles or cargo rockets. Besides, it's important as the space station is about to expand from three people living on board to six. The recycling system had been brought up to the space station last November by space shuttles Endeavour, but it couldn't be used until samples were tested back on earth. So when it came time to actually drink up, NASA made a big deal of it. The three-man crew stood holding their drinks and congratulated engineers in two NASA centres that worked on the system. "This is something that had been the stuff of science fiction," American astronaut Michael Barratt said before taking a small mouthful. "The taste is worth trying." The new system takes the combined urine of the crew from the toilet, moves it to a big tank, where the water is boiled off, and the vapor is collected. The rest of the urine is thrown away. Then the water vapor is mixed with water from air, and then it goes through filters . When six crew members are aboard it can make about six gallons from urine in about six hours. "Some people may find the idea of drinking recycled urine distasteful, but it is also done on earth, but with a lot longer time between urine and the tap," said Marybeth Edeen, the space station's national lab manager.

mmlu_train_65508 | Food safety will become the food industry's key target as the nation tries to adopt international food standards. The National Development and Reform Commission, the Standardization Administration of China, the Ministry of Agriculture and six other departments announced their 2004-05 development programme for national food standards over the weekend. China is conducting a rectification within two years. Inspectors will search for all known banned materials in food production. To reduce trading barriers, China will raise the ratio of adopting international standards in the food industry to 55 percent from today's 23 percent. "Safety is the first consideration for anything entering people's mouth followed by its nutritious value," said Hao Yu, secretary-general of the National Food Industry Standardization Technique Committee. He added the usage of food addictives will be a major field for consideration in setting the new standards. On-the-spot checks during the past two years have shown the abuse or misuse of addictives in food production and processing has become the biggest threat to food safety. In one case, talcum powder was found in flour products, which is outlawed according to national food standards. "At present there are no methods or standards to test the content of talcum powder in flour," said Shang Yan'e, an official with the national watchdog on grain and oil inspections. Under the guidelines, all banned addictives will be recorded as inspections increase, Relevant departments have allocated funds to conduct risk evaluations on current food addictives to fix the limits of their usage. China will adopt international advanced techniques and standards so as to find out the harmful materials in food within a shortest period. What does the passage mainly talk about? | [

mmlu_train_7552 | Look, this is the first plane in the world to be created using the new technology of "3D printing". The airplane was built using only a computer--but it can fly at a speed of 100mph and has a two-meter wingspan. It was produced using a special nylon laser printer that builds up something layer-by-layer. The parts were made separately and attached using a "snap fit" technique so the aircraft could be put together without tools in minutes. No fasteners at all were used in the manufacture of the plane. Unmanned and electrically powered, the plane can travel in near silence and is also equipped with a small autopilot system. The special production process used is known as "laser sintering "and allows the designers to create shapes and structures that would normally include costly manufacturing techniques. This technology allows a highly-tailored aircraft to be developed from your own design to first flight in days, while using traditional materials and techniques would take months. And because no tooling is required for manufacture, major changes to the shape and scale of the aircraft can be made with no extra cost. Professor Jim Scanlon, who led the team, said, "The process allows the design team to revisit historical techniques and ideas that would have been too expensive using traditional manufacturing." He added, "This form of structure is very firm and lightweight, but very complex. If it was manufactured traditionally it would require a large number of individually tailored parts that would have to be connected or fastened at great expense." The new printed plane is known as the Southampton University Laser Sintered Aircraft--or SULSA for short--and is part of a wider project using cutting-edge manufacturing techniques. The University of Southampton has been at the leading position of Unmanned Aerial Vehicle development since the early 1990s. Professor Jim Scanlon believes they can _ with their techniques. | [

mmlu_train_17719 | Holding a cell phone against your ear or stalling it in your pocket may be hazardous to your health. This paraphrases a warning that cell phone; manufacturers include in the small print that is often tossed aside when a new phone is purchased.Apple, for example, doesn't want iP hones to come closer to you than 1.5 centimeters; Research In Motion, Blackberry's manufacturer, recommends 2.5 centimeters. If health issues arise from cell phone use, the implications are huge.Voice calls - Americans chat on cell phones 2.26 trillion minutes annually - generate $109 billion for the wireless carriers. Devra Davis, an epidemiologist who has worked for the University of Pittsburgh, has published a book about cell phone radiation, "Disconnect." The book surveys scientific research and concludes the question is not settled. Brain cancer is a concern that Ms. Davis examines. Over all, there has not been an increase in its incidence since cell phones arrived. But the average masks an increase in brain cancer in the 20-to-29 age group and a drop for the older population. "Most cancers have multiple causes," she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer. Children are more vulnerable to radiation than adults, Ms. Davis and other scientists point out. Radiation that penetrates only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid. No studies have yet been completed on cell phone radiation and children, she says. Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiofrequency radiation had damaged DNA in their brains. Ms. Davis recommends using wired headsets or the phone's speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the abdomen. From this passage we can learn that. _ . | [

The bird has green, orange, blue, red, yellow, purple and grey colors on its body. Rainbow lorikeets are small birds. They are usually 11 to 12 inches long and weigh 120g to 140g. It is said that they can live for over 20 years in the wild. They usually live in groups. At night, they sleep in the trees in a big group. But during the daytime, they move in much smaller groups (about 20 birds). Late in the evening, you can sometimes see a larger group flying back home. These birds spend a lot of time looking for food. Most of their food comes from trees, like flowers, nuts and fruit. But sometimes they eat insects. They can get water from the leaves that they eat or drink water directly. Rainbow lorikeets usually start to have families when they are around two years old.

mmlu_train_42568 | Women turn to online shopping Women have jumped ahead of men for the first time in using the Internet to do their holiday shopping, according to a study published last week in the US. For years men have been more likely to shop on the Internet than women, but during the 2004 holiday season, 58 percent of those making online purchases were women. "It shows how mainstream the Internet is becoming," said Lee Rainie, director of the Pew Internet and American Life Project group, which carried out the study. Rainie said it was only a matter of time before women shoppers caught up with men. This is because women traditionally make decisions about spending. Users were more likely to shop online to save time. Internet users between the ages 18 and 29 were responsible for some of the most dramatic increase in the online gift-buying population this time around. However, three- quarters of the US Internet users did not buy holiday gifts online in 2004. They worried about credit card security, or just compared online prices with off-line prices, then dashed off to the shops to get the best deals. " But even if shoppers don't buy online , websites are becoming promotion tools for stores," said Dan Hess, vice president of ComScore Networks Inc. Hess said that actually most stores' websites can make customers fully believe the security of their credit card numbers. And most are able to ensure that gifts arrive on time.

"I've decided to apply for the test to enter a medical college to become a doctor, changing from my original plan to prepare for a lawyer qualification exam in order to get a more stable job in the future," said a 24-year-old college graduate, Lee, who majored in business administration during his undergraduate schooling. The new medical and dental school system is getting popularity, attracting an increasing number of students every year since its appearance in 2004, as it is open to all college graduates regardless of their previous majors. The Education Development introduced the new medical and dental education system, in which college students with bachelor's degrees are allowed to study medicine or dentistry by taking the Medical Education Test (MET) and Dental Education Test (DET). Ten medical schools and six dental colleges that have used the new system have received 4,377 applications for the entrance exams. Applicants are getting younger compared with those in their 20s representing 76.9 percent of the total. The tests might be easier for students with biology and chemistry majors, but graduates from other majors are also applying for the tests. Under the existing medical and dental education system, students should take a two-year premedical course followed by a four-year medical course. Students graduating under the new medical or dental education system are given master's degrees, while those graduates who studied under the previous system have bachelor's degrees. Students in the old system may spend _ years at college to get bachelor's degrees. | [

mmlu_train_23464 | Almost anyone who has read a travel brochure about Africa has heard of a story ----- that elephants can get drunk by eating the fermented marula fruit rotting on the ground. Books have even been written to prove the truth of the phenomenon. But a study published in the journalPhysiological and Biochemical Zoologytells a very different story. Steve Morris, a biologist at the University of Bristol in England and an author of the study, says there is nothing in the biology of either the African elephant or the marula fruit to support the stories. Morris says, "People just want to believe in drunken elephants." The marula tree, a member of the same family as the mango , grows widely in Africa. Its sweet, yellow fruit is used for making jam, wine and beer. "The first mistake of the drunken-elephant theory is that it's unlikely that an elephant would eat the fruit if it were rotten," Morris says. "Elephants eat the fruit right off the tree, not when it's rotten on the ground," he explains. Other experts add that if an elephant were to eat the fruit on the ground, it wouldn't wait for the fruit to ferment. Michelle Gadd, an African wildlife specialist, says that elephants and many other animals, including birds and monkeys, are too fond of marula fruit to let it rot. If fermented fruit on the ground is out of the question, so is the concept that the fruit could ferment in the stomach of elephants, according to the study authors. Food takes between 12 and 46 hours to pass through an elephant's digestive system, the authors point out, which is not enough for the fruit to ferment. Supposing that _ happened, it's still highly improbable that the food would produce enough alcohol to make an elephant drunk. Through calculations of body weight, elephant digestion rates, and other factors, the authors conclude that it would take about 1.9 litres of alcohol to make an elephant drunk. Which of the following is Mr. Morris's opinion? | [

Apple has launched a new iPhone every year since it unveiled the range in 2007, selling more than 500 million units since then, and has traditionally launched key products in September. The iPhone 6, Apple's ninth iPhone model, is expected to be released in two different sizes:4.7-inches and 5.5-inches. The smaller of the two will be available first. Like iPhone5, the new model will come in silver , gold and space grey. The iPhone 6 will be powered by new operating system iOS 8. Through iOS8, users will be able to monitor their health and fitness via HealthKit. HealthKit puts together numerous healthcare and fitness apps, such as blood pressure and heart rate monitors through partners including Nike, and allows them to communicate with each other. Users will be able to control home appliances and other connected devices through HomeKit, Apple's connected home framework. Similar to HealthKit, this app will organize your smart devices to control them in one place. One method of control will be via Siri-for example, you could tell Siri you were "going to bed", and it could dim the lights, lock your doors, close the garage door and set the room temperature. With the introduction of both of these key features, it's likely the iPhone 6 will take on even more of a lifestyle device role. It is designed to organize our lives and make everyday tasks easier and more efficiently completed. Suppliers are believed to be preparing to produce up to 80m of the new handsets by the end of December, according to the Wall Street Journal.

mmlu_train_10311 | Older fathers have uglier children, researchers have claimed after linking age to genetic mutations . The finding comes weeks after leading scientists reported children born to men over the age of 45 run a higher risk of having autism and mental disorders. With age, sperm -producing cells do not copy a man's DNA as effectively, leading to genetic mutations. Martin Fielder, an anthropologist at Vienna University, told the Sunday Times: 'Every 16 years the mutation rate doubles. Other researchers found 25 mutations per sperm in a 20-year-old, but at age 40 it is 65 mutations. By 56, it doubles again. The effect is very visible - someone born to a father of 22 is already 5-10 per cent more attractive than those with a 40-year-old father and the difference grows with the age gap. In contrast, women pass on a maximum of 15 mutations to their baby, regardless of age, according to the study published in the journal Nature. Surveying a group of six men and six women, researchers showed them each 4,018 photographs of 18-20-year-old men and 4,416 of women the same age, and asked to assess their attractiveness. Those with older fathers were consistently considered less attractive. However, the children of older men, though less attractive, are likely to outlive their peers with younger fathers, it is claimed. Professor Lee Smith, a geneticist at Edinburgh University, told the Sunday Times other research found such children have longer telomeres - the caps on the end of chromosomes --- which are associated with longer life. But the mounting research connecting parents' age with autism is cause for concern, experts warn. Autism is an umbrella term for a range of developmental disorders that have a lifelong effect on someone's ability to interact socially and communicate openly. In the UK, around one in 100 adults is thought to be affected by autism, mostly men, caused by a combination of genetic and environmental factors. Researchers said men should be advised about the potential problems in order to help their personal decision-making when it came to having fathering children at older ages. They warned that advancing paternal age faced a risk of 'numerous public health and societal problems'. Among well-known older dads are Simon Cowell, 54, whose son was born earlier this month, and comedian Frank Skinner whose first child was born in 2012 when he was 55.
